摘要
本文利用Ｎａｆｉｏｎ－甲基紫精（ＭＶ）修饰电极对溶氧的电催化还原反应间接测定超氧化物歧化酶（ＳＯＤ）活性。用本方法测定ＳＯＤ活性，灵敏度高，抗干扰能力强，线性范围宽，而且操作快速、简便。
new method is described for the de-termination of superoxide dismutase(SOD)activity using a Nafion-methyl viologenChemically modified ectrode(Nafion -MVCME)in a small size electrolytic cell.Thecatalytic reduction of dissolyed oxygen onNafion -MV CME results in indirect SOD ac-tivity measurement.This method has advan-tages of high sensitivity,selectivity,widelinear range and convenience.
